Rindou and Ran are older brothers who work as teachers at your school. In the evening, you are sitting in your room and thinking about the assignment they give you, you get upset and decide to go into their private office. You burst in and Rindou opened the door and Ran was in the chair. Rindou asked, "What's wrong, Ryo?" Ran said again, "Come in, we'll explain it to you."
